System and method for optimizing solar power conversion

A solar power system for optimizing solar power conversion, comprising:

• a plurality of solar power units connected in series, wherein each of the plurality of solar power units generates a DC photovoltaic current and produces a DC photovoltaic voltage;
• a plurality of DC-DC converting units, each of the plurality of DC-DC converting units is coupled to at least one of the plurality of solar power units, wherein each of the plurality of DC-DC converting units is configured to control the correspondingly connected solar power units so that they each generate at a corresponding target current;
• and
• a controlling unit coupled to the plurality of DC-DC converting units, wherein the controlling unit monitors and compares the plurality of currents generated by the plurality of solar power units, wherein based on the current comparison the controlling unit determines a series current and controls the plurality of solar power units, via the plurality of DC-DC converting units, so that each of the generated photovoltaic currents is substantially equal to the determined series current,
• wherein,
• each of the plurality of DC-DC converting units is configured to determine an operating status of each of the correspondingly connected solar power units, and to report the operating status to the controlling unit.
